+Amazon Kindle 4/5 Model No. D01100, D01200 and EY21
+===================================================
+
+The Kindle Model No. D01100 (Kindle Wi-Fi), D01200 (Kindle Touch)
+and EY21 (Paperwhite) are refered as the Kindle 4th and 5th generation.
+Those e-book readers share a common set of hardware:
+
+* a Freescale i.MX50 SOC
+* 2 or 4GiB eMMC
+* a MC13892 PMIC
+
+The older readers D01100 and D01200 use 256MiB of LPDDR1,
+while the newer EY21 uses 256MiB of LPDDR2.
+
+The devices boot up in internal boot mode from an eMMC boot partition and
+are shipped with a vendor modified u-boot imximage based on u-boot v2009.08.
+
+To upload and run a new bootloader the older devices can be put into
+USB-downloader mode by the SOC microcode when a specific key is pressed during
+startup:
+* the fiveway down button on the model D01100
+* the home button on model D01200
+A new USB device "NS Blank CODEX" should appear, barebox may be uploaded using
+$ scripts/imx/imx-usb-loader barebox-kindle-d01100.img
+$ scripts/imx/imx-usb-loader barebox-kindle-d01200.img
+Hint: keep the select button pressed down to get the barebox USB console.
+
+Barebox may be used as drop-in replacement for the shipped bootloader, when
+the imximg fits into 258048 bytes. When installing the barebox imximg on
+the eMMC take care not to overwrite the vendor supplied serial numbers stored
+on the eMMC.
+e.g. for the D01100 just write the imx-header and the application section:
+loady -t usbserial
+memcpy -b -s barebox-kindle-d01100.img -d /dev/disk0.boot0.imx_header 1024 0 2048
+memcpy -b -s barebox-kindle-d01100.img -d /dev/disk0.boot0.self 4096 0 253952
+
+Note: a USB serial ACM console will be launched by a barebox init script
+when
+* the cursor select key is pressed during startup of model D01100
+* the home button is pressed within a second after startup of model D01200.
+ If you press the home button during startup, you will enter USB boot mode.
+* the EY21 has no keys to press, a USB console will be launched for 10s.
+
+This device is battery-powered and there is no way to switch the device off.
+When the device is inactive, the kindle software will first reduce the
+power consumption to a few milliamps of battery power, after some minutes
+the power consumption is further reduced to about 550 microamps. Switching
+on iomux pullups may significantly reduce your standby-time.
+
+Hints to reduce the build image size.
+Note that a drop-in replacement barebox imximage must not exceed 258048 bytes
+since the space behind it is in use. Hence, don't build in drivers and FS
+that are not required, e.g.:
+ NET, DISK_AHCI, DISK_INTF_PLATFORM_IDE, DISK_ATA, VIDEO, PWM, LED,
+ USB_STORAGE, USB_ULPI, NAND, MTD_UBI, FS_UBIFS, MFD_MC34704, MFD_MC9SDZ60,
+ MFD_STMPE, EEPROM_AT25, EEPROM_AT24, KEYBOARD_GPIO, PARTITION_DISK_EFI
+Also unselect support for other boards to get rid of their dependencies.
+Further select IMAGE_COMPRESSION_XZKERN
